Hotline:
A flywheel device, as a high-speed rotating mechanical component, can be used forsimulating the moment of inertia of the rotor in a real transmission chain systemto truly reflect the physical characteristics and operating conditions of the test piece's power source system. In addition, the flywheel rotor absorbs energy when the rotor's angular velocity increases and releases energy when the angular velocity decreases. It is also used in rotary motion tostore rotational kinetic energy, a mechanical device; it can be used to absorb the periodic speed fluctuations of rotating parts during operation. The flywheel tends to resist changes in speed. When a dynamic torque acts on the rotating shaft from the power source (e.g., a reciprocating engine), or when used with an intermittent load (e.g., a piston or press),the flywheel can reduce speed fluctuations, making the rotation smoother; other functions:using a smaller power prime mover to quickly drive a working machine that momentarily requires larger power; helping the machine start and overcome dead points.
Application Range of Inertia Flywheels
1. Used in aero-engine test benches, installed after the hydraulic dynamometer to simulate the load inertia of the engine transmission chain;
2. Used in generator/motor test benches to simulate system rotational inertia; such as traction motor test benches, vehicle drive motor test benches, etc.;
3. Used in vehicle test benches to simulate inertial loads during vehicle start-up and braking.
4. Used in brake test benches to simulate the physical inertia of the braking system; including rail wheel brakes, vehicle brakes, tank brakes, etc.;
Application Case
The aero-engine test bench inertia flywheel group is applied to a test bench of a certain military enterprise. Through continuous operation of the engine's long test, the performance is stable, and all indicators meet the design and customer requirements; multiple products have been delivered, and the products have received positive customer feedback.
Product Significance
Under the severe situation of foreign blockade, it successfully replaced imported products from abroad, contributing to the completion of the test tasks for a certain engine Model.
